MultiValueDictKeyError / request.POST

Change:

def add_post(request):
    entry_title = request.POST["title"]
    return HttpResponse('Hello %s' % entry_title)

to:

def add_post(request):
    entry_title = request.POST.get("title", "Guest (or whatever)")
    return HttpResponse('Hello %s' % entry_title)

and it won't throw a KeyError, but you should look at using Django's forms rather than pulling values directly from the POST data.

Alternatively, you can keep your existing code and simply check for the exception:

def add_post(request):
    try:
        entry_title = request.POST["title"]
    except KeyError:
        entry_title = "Guest"
    return HttpResponse('Hello %s' % entry_title)

but this is what .get() does internally already.

I had the same problem, I discovered that I forgot to add "name=" text" " in my input type in my Html page..
